ICD-10 Code E30.0 – Delayed puberty (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E30.0 – Delayed puberty
What it is
E30.0 identifies delayed puberty, meaning pubertal development starts later than expected. Use this code when documentation states delayed or absent pubertal progression without a more specific underlying cause.
Clinical signs
Typical findings include absent or slow development of secondary sexual characteristics and delayed growth-related pubertal changes. Clinical features vary; refer to documentation.
When to use this code
Use E30.0 when the clinician documents delayed puberty as the diagnosis, especially during endocrine or adolescent evaluations. Apply it when the record describes late pubertal onset or stalled pubertal progression and no alternate diagnosis is documented. Check documentation if an underlying disorder is also identified.
Do not use for
Do not use this code for normal variation in pubertal timing without a diagnosis. Do not use it when the delay is better explained by another documented condition; code the underlying disorder instead.
Coding tip
Verify that the provider explicitly documents delayed puberty and note any identified cause before assigning E30.0.
